A wall that is built to support the above slabs or other building elements in a structure is called a load bearing wall.
In load-bearing wall buildings live and dead loads are transferred to the ground through designed walls and foundations.
The most commonly used materials for constructing load-bearing walls in massive buildings are concrete, blocks, or brick.
Function of Load Bearing Wall:
- It carries the load of a home from the roof and upper flooring.
- Load-bearing walls transfer loads all the way to the foundation or other suitable frame members.
- It can assist structural members such as beams, slabs, and walls on flooring above.
- Load-bearing walls also carry their own weight.
- This wall is normally stacked on each flooring.
- Load-bearing walls can be used as an interior or exterior walls.
- Such walls will usually be perpendicular to the floor joist or ridge.
- Concrete is a perfect material to support these loads.
Types of Load Bearing Wall:
Precast Concrete Wall:
This precast concrete wall is aesthetically pleasing, this precast wall has higher strength and it is identified for sturdiness.
It offers excellent protection and they are simple to install.
Retaining wall offers lateral support, installing a retaining wall has many environmental advantages such as lowering erosion and protecting areas from being saturated.
It is also generally known as a revetment or breast wall.
Masonry is the most durable part of any structure because it allows for unlimited architectural expressions.
They provide strength durability.
The masonry wall also helps in controlling the temperature in indoor and outdoor.
In addition, it increases fire resistance, the lateral hardness of the masonry wall is very low.
Pre-paneled load bearing metal stud wall:
It is used to manufacture exterior wall cladding.
The metal can be stainless steel, copper, aluminum, it supports gravity, seismic and wind loading.
Engineering Brick Wall:
It uses a double open-ended bond beam block constructed using a mold.
The block wall is replaced horizontally.
It is considered as a stone structure.
This wall gives structure to a building and encloses an area.
Advantages of load bearing wall:
- It is good and inexpensive for building less than 2 floors construction because bricks are cheaper.
- Also, good against fire resistance as rebars in RCC may fail by melting in fire.
- It has a thick brick wall, which gives the walls more weather resistance, noise protection.
Disadvantages of Load Bearing Wall:
- Brick foundations require large foundation area as compare to RCC framed structure because the load carrying capacity of brick is much lower than that of RCC.
- This gives less available area.
- Load-bearing structure is poor in resistance to earthquakes because shock waves create irregular stresses and compression in columns.
- Tension is greatly developed by RCC steel which is absent in the load-bearing structure.
Load-bearing structures are those structures where the total load of the building is tolerated by the building walls
